Gene knockout is a term used to describe the process of deactivating a specific gene in an organism. This technique is widely used in genetic research to study the function of genes and the impact of their absence on the organism under study. There are other synonyms for gene knockout that are used interchangeably, such as gene inactivation, gene deletion, and gene disruption. These synonyms are all different ways to refer to the same process that involves either removing or disabling a specific gene from an organism's DNA sequence. Gene knockout and its synonyms are vital tools in modern genetic research and have contributed to significant breakthroughs in various fields.
